With the development of science and technology, there are more and more vegetable cultivation methods. Among them, pollution-free organic vegetables are the most popular among consumers. Today, Hui Nongwang Xiaobian will share with you the cultivation techniques of pollution-free organic vegetable seedlings, and growers will hurry. study! Cultivation techniques for pollution-free organic vegetables and seedlings: The current method of planting vegetables and seedlings is to plant vegetables and seedlings directly on the ground, then watering and fertilizing. This traditional planting method has the following defects: (1). During the planting process, vegetables and seedlings need to be watered with a lot of water, but they are really absorbed by vegetables and seedlings, which is very wasteful of water resources; (2). Vegetables and nurseries need to be manually watered and fertilized in the process of planting, which is very wasteful of labor: (3) Limited by the conditions of cultivated land, no land can be planted without land. 1. Collecting and treating the biogas slurry: first collecting the biogas slurry; then adjusting the concentration according to the requirements of the growth of the vegetable to adapt to the concentration of the biogas slurry, and testing the biogas slurry; 2. Solidification of biogas slurry: 8% to 15% of expanded perlite is mixed with 75%-92% of biogas slurry by weight, so that the expanded perlite absorbs the biogas slurry and solidifies into pellets; 12% of the expanded perlite is mixed with 88% of the biogas slurry. 3. Formulating the cultivating base; 60%-90% of the volume of the container placed in the bottom of a container has sucked the solid particles of the biogas slurry, and covers 10%-40% of the volume of the container in the upper part thereof. Preferably, 75% of the volume of the container placed in the bottom of the container has absorbed the solid particles of the biogas slurry and covers 25% of the volume of the container at its upper portion. The vegetables are grown on a cultivating base in a container. The preparation of the cultivating base may also be carried out by mixing the soil with the expanded perlite which has absorbed water and fertilizer, and then placing it in a trough container. We can build a pig farm and a pollution-free organic vegetable planting base in the greenhouse, and build an anaerobic biological fermentation ground (ie, biogas tank) in the middle. The size of the pig is determined by how much biogas slurry can be produced or how much biogas slurry is consumed. In this way, the pigs are raised with feces, biogas produced by anaerobic organisms, biogas slurry and biogas residue, biogas can be used as fuel, and biogas slurry meets the demand for planting pollution-free organic vegetables in greenhouses. The biogas residue is used to process and cover the soil, and the excess part is used as an ecological balance breeding model for commercial organic base fertilizer. It is also possible to use the dung of urban residents instead of pigs. The pollution-free organic vegetable cultivation technology is simple, and the nutrition is healthy. At present, the market prospect is broad, and the growers have to learn quickly!
